  • In this paper, we proposed the novel device and process design to enhance the uniformity of low-temperature poly-Si TFTs fabricated by sequential lateral solidification (SLS). The proposed design schemes can avert the conventional two-shot SLS process-induced issues. Moreover, different design considerations between conventional excimer laser crystallization and the SLS process were also proposed and discussed.

  • An m-transversal to a family of convex sets in the plane is an m-point set which intersects every members of the family. One of Grubaum's conjectures says that a planar family of translates of a convex compact set has a 3-transversal provided that any two of its members intersect. Recently the conjecture has been proved affirmatively (see [4]). In the present paper we provide a different and straightforward proof for the conjecture for the family of translates of a closed trapezoid in the plane and give several concrete 3-transversals.

  • In 1970 Monsky proved that a square cannot be cut into an odd number of triangles of equal areas. In 1990 it was proved that the statement is true for any centrally symmetric polygon. In the present paper we consider dissections of general polygons into triangles of equal areas.

  • Based on the test data of Nippon Steel Corporation, the formulas for calculating mechanical properties of fire-resistant (FR) steel at elevated temperatures have been established. A practical approach for fire safety design of FR steel members, including axially compressed members, flexural members and eccentrically compressed members, is developed in this paper. Compared with the full-scale specimen experiments and FEM numerical analysis, this practical approach for fire safety design of FR steel members is demonstrated to be effective and precise.

  • Three grayanane diterpenoids (1-3) were isolated from Pieris formosa. 1 was identified as a new natural product and 2 and 3 as known grayanoside C and grayanotoxin XVIII on the basis of spectral analysis.
